An Unconstrained Voltage Support Scheme for Distributed Generation Connected to Resistive-Inductive Grid Under Unbalanced Conditions

In several countries, during the grid faults, the large distributed generation (DG) is expected to support the voltage at the point of common coupling, as per the prevailing grid code. Large DGs are connected to a high voltage transmission line, where the voltage support is achieved by supplying the reactive power. The recent research trend, however, is toward voltage support by the medium size DG...
